LOGGING BOAT.

Application filed October as, 1927. Serial No. 229,384.

The present invention relates to boats and particularly to boats adapted for use in logging.

Objects of the invention are to produce a logging boat simple in construction and effective in operation, which will be lightto handle and effective in locomotion through vines, water plants and other obstructions.

Further objects are to provide a boat with comparatively great draught power and in which the propelling mechanism will sustain its own weight in the water and assist the buoyancy of the boat as a whole.

Other objects and advantages will appear from the following description and willbe set forth in the appended claim, and I do not wish to be limited in the, scope of my invention except as I shall be limited by said claim.

In the drawings:

Figure 1 is a plan view of a boat constructed in accordance with the principles of the invention.

Figure 2 is a side elevation of the same.

Figure 3 isan enlarged fragmentary view in longitudinal section through one of the propelling drums and showlng the relation of the propeller blades to the drum and the arrangement on the drum for mounting a drive chain thereupon.

Figure 4 is a section on the line 44 of Figure 2, showin fragmentarily guide rollers for theguiding chain, the view belng on an enlarged scale compared with Figures 1 and 2.

Referring to the drawings in detail, 10 designates a platform which may be made in the form of a closed compartment having side walls 11 and end walls 12 and a bottom 13, the purpose of which is to ncrease the buoyancy of the platform. Plvotally secured to the front and rear ends of the platform by means of a bracket 14 having straps 15 secured to the top and bottom of the'platform,are yokes 16 and 17 having hollow hermetically sealed drums 18 and 19 rotatably mounted thereon by means of pinions 20 journaled in the arms 21 and 22 of the yokes 16 and 17. V The drums are provided with L-shaped angle irons 23 secured V V longitudinally of the periphery of the drum and having one arm 24 of each of said members extendlng radially from said drum to form propeller blades on the drum, which passed between guide members: 29 having anti-friction guide rollers 30 and 31 arranged respectively above and below the chain rollers 32 and 38 on either side thereof. The brackets 16 and 17 are pivotally connected with the bracket 14 by means of king pins34.

The boat is directed in its course through the water by means of a steering wheel 35 connected to the platform by the steering shaft 36 which is provided near the upper surface of the platform with lever arms 37 to the ends of which are secured the ends of cables 38, 39, 40 and 41, the first two named cables forming a connection with the sides of the yoke 17, as at 42 and 43, the cables 40 and 41 connecting the arms 37 to the sides of the yoke 16, as at 44 and 45. It will be noted that with this connection when the wheel 35 is turned clockwise in accordance with the showing in Figure 1, the bracket 17 will be turned to the right, as will also the rear bracket, and the opposite will occur when the wheel is turned in a counter-clockwise direction.

From the foregoing description it will appear that I have made a boat, the construction of which makes for lightness in that the propeller blades are located on hermetically sealed hollow drums and the platform supported thereby is itself a hollow member. The arrangement is particularly adapted for operation in shallow water and in water where there is a considerable growth of weeds and water plants to be contended with. The device having a propeller drum at each end extending the whole width of the platform, affords great propulsive strength and is capable of great pulling force in case the boat is to be utilized in dragging logs out of the swamps and the like. 7

Having described the invention, what is 5 claimed is:

A boat, comprising a, buoyant central section, carrying a, power unit, a forward and rear pivoted buoyant drum with peripheral transverse paddles, a sprocket chain cen-r trally of the paddles, driven by the power unit, and a steering post carrying cliametri-j ,,EDWARD B. ALLEN.
